DETERGENT.

No Drawing.

New York, and State of New York, have invented new and usefulImprovements in Detergents, of which the following is a full, clear, andexact specification. Our invention relates to detergents and refersparticularly to detergent soaps.

We have found that cymene and the salts of the sulphoacids of cymenepossess extraordinary and highly valuable detergent properties capableof practical application in the production of soaps and similarproducts. The value of these products for detergent purposes is enhancedby our discovery that they are soluble in saponaceous bodies, thusmaking them suitable for incorporation with saponified fat andsaponified oil soaps with the production of products having detergentvalues greatly in excess of the soaps not so incorporated. I i

Without entering into a discussion of the several theories regarding thechemical and physical conditions and reactions incident to detergentbodies and their use, we,would state that cymene and these cymenecompounds have the characteristics of colloids, possessing highviscosity and low surface tension, in addition to which they possessstrong emulsifying properties. i

We have found that cymene and the salts of the sulphoacids of cymene maybe incorporated with saponaceous bodies, either after, or during, theiremulsification, producing resulting compounds, or mixtures, possessinghigh detergent, antiseptic and germicidal properties. e

We have further found that cymene and 41 the salts of the sulphoacids ofcymene have strong odor destroyin properties and that their use inconjunctlon with odoriferous saponaceous bodies will destroy the odors,thus producin odorless, or practically odorless, compoun s. 7

Application filed August 26, 1921.

Serial No. 495,760.

We have found, for example, that when 2% of sodium cymene sulphonic acidare added to a soap composed of saponified fat, the detergent propertiesof the original saponified fatshave been increased 65% and that, at thesame time, the resulting product is odorless, antiseptic and ermicldal,thus possessing greatly increased value over the original saponifiedfats.

The addition of cymene and the salts of the sulphoacids of cymene willconvert soft soaps, such as oleic acid soaps, into hard soaps,irrespective of whether the cymene or the salt of the sulphoacid ofcymene is added during, or after, the production of the soap. This is amost valuable attribute of these chemicals.

By cymene we mean either the chemically, or commercially, pure cymene,or the crude cymene-of the waste sulphite turpentine, obtained as aby-product in the production of paper. 1

By salts of the sulphoacids of cymene we mean those salts of the mono-,or multi-, sulphoacids of cymene which are dissolvable, or miscible,with the particular saponaceous body with which they are employed,producing results having detergent powers greater than the employedsaponaceous body.

Among the salts of the sulphoacids of cymene which we have foundparticularly valuable are the alkali salts, such as sodium,

potassium and ammonium salts of the sulphoacids, although other saltshave valuable properties for particular uses.

For clearness of definition and classification, we employ the wordscymene bodies in our claims to mean cymene and salts of the sulphoacidsof cymene, as described A above.

. or one salt of a su phoacid of cymene, or'a mixture of several, may beemployed and a singlesaponaceous body, or a mixture. of several, mayalso be employed WVe do not limit ourselves to the particular 2.
